Video: Livernois Motorsports’ Stage 3 Z06 Runs In The Mid-9s

Livernois Motorsports [1] of Dearborn Heights, Michigan has managed to squeeze massive horsepower out of a nitrous-fed ’08 Z06 using a substantial performance upgrade that they call their “Stage 3” conversion. A combination of head and cam tweaks, the upgrade is good enough to make 630 rear wheel horsepower on the motor alone and 729 on the bottle.

But according to Livernois [1], the 100-shot of juice on their Stage 3 was actually a little bit of an overkill; the Dearborn Heights builder claims that the red Z06 was actually capable of running a 9.93 pass at 139 MPH naturally aspirated. The Stage 3 conversion itself, however involves much more than just a radical nitrous boost.

Livernois’ valvetrain upgrade consists of their in-house, Stage 3 cam ground specifically for the LS7 mill and tapping a set of dual valve springs. Also helping the LS7 to breathe massive air is a 102mm intake from FAST [2] and a cold air system from Halltech [3]. [4]

The 729-horse Z06 was tuned by Livernois and uses a set of long tube headers and an x-pipe from Kooks [5] to exhale all of its unbridled fury. In our featured video, we see firsthand how all of their Stage 3 tweaks have paid off as the red ‘Vette runs a 9.51 pass at 148.59 MPH with a stock transmission, bottom end, rearend and half shafts.

The nitrous-shot might have been, as Livernois Motorsports claims, a bit too much for an LS7-powered freak of nature that was already pushing 630 wheel horses to begin with. But with a mid-9 second pass in a ‘Vette that’s using a stock gearbox and a factory rear, we’re glad that they went that route anyway!
